The Sowing and Germination of Haworthia
Today's sharing: an introduction to the knowledge of Haworthia, a type of succulent plant, including the sowing and germination of Haworthia. Here is the detailed introduction.
Haworthia refers to the seeds of genera such as Xianzhang, Yushan, and Shou. Haworthias belong to the Lily family, and their root systems are renewed every year. Before sowing, soak the seeds of Haworthia in warm water for 10-15 minutes. This method has been discussed in the early issues of the Haworthiad magazine, which may be a hypothesis (an unverified theory), but it often works well. If you have difficulty germinating Haworthia seeds, why not try it?
1. Before sowing seeds, you need to control your temperature above (15°C) and below (20°C), cycling in this temperature difference every day, which is the best sowing temperature. Lithops also thrive in this temperature range.
2. It is not suitable to sow seeds in summer. If the temperature exceeds (27°C) in summer, it will hinder germination. The temperature for germination should be reduced to (21°C) at least for part of the day.
3. The cultivation soil used for sowing should include peat, which when soaked in very hot water is believed to release ethane gas. The release of this gas is thought to help break down any factors that inhibit germination present on the seed coat. Also, mix some coarse sand at the bottom of the peat, with a diameter of 2-3 millimeters. Generally, the ratio is 1:1, not by weight, but by volume.
4. The sown seeds should be on the surface of the sowing substrate, under scattered light of medium brightness, to achieve a higher germination rate. It may not seem that important, but some varieties have been proven not to germinate at all in complete darkness, so do not place them in a dark place.
5. The pots and cultivation soil should be sterilized with a microwave or boiling water to reduce losses caused by moss, insects, etc.
6. After spreading the seeds on the potting soil, cover them with plastic wrap and pierce some small holes, about 10 holes in a 10X10 pot, to facilitate ventilation, generally 5-10 holes in a 10 cm pot.
7. Generally, it will start to germinate after waiting for about two weeks. Some species only need 2 days from sowing to germination, while Haworthia may take up to 2 months or more to fully emerge, so do not despair and decide if it has not germinated after 2-3 months. Don't throw them away too soon!
8. After germination, use a spray bottle to gently water the plants frequently. During the seedling stage, keep the potting soil moist. If you see any mycelium, you can spray a fungicide to reduce the risk of gray mold disease, which is mysterious yellowing and watery.
9. As soon as you feel that most of the seeds have started to germinate, frequently open the plastic wrap, basically covering it during the day and keeping it ventilated at night to avoid gray mold disease affecting your precious seeds.
10. Maintain a relatively warm temperature, with seedlings at a minimum of (10°C), so they can grow well. A spacious and bright balcony is a suitable place for the required sunlight, but remember not to expose them to direct sunlight, especially during noon.
The above is a detailed explanation of the sowing and germination of Haworthia, for everyone's reference and suggestion!
